摘要

本文根据近年来的收集和野外观察，重新恢复了m.s rostratum Thwaites的异型同义种Memecylonelegantulum Thwaites。两种植物的主要区别在于习性、花序结构、花形态和片层形态。一个选型和一个表型被指定为Memecylonelegantulum，一个选型被指定为M.rostratum。这两个物种都局限于斯里兰卡西南部过湿润的“湿区”的混合龙脑雨林。Memecylonelegantulum在Ratnapura地区的分布范围相对较小，而M.rostratum在潮湿地区的分布范围较广。

Reinstatement of Memecylonelegantulum (Melastomataceae) and recircumscription of Memecylonrostratum, two species endemic to Sri Lanka.

Memecylonelegantulum Thwaites, a heterotypic synonym of M.rostratum Thwaites, is re-instated based on recent collections and field observations. The two species differ mainly in their habit, inflorescence structure, floral morphology and lamina morphology. A lectotype and an epitype are designated for Memecylonelegantulum, and a lectotype designated for M.rostratum. Both species are confined to the mixed dipterocarp rainforests of Sri Lanka's perhumid south-western 'wet zone'. Memecylonelegantulum appears to be restricted to a relatively small range in Ratnapura district, while M.rostratum has a wider distribution in wet zone.
